The KDCJ-20Z touch screen intelligent impulse withstand voltage tester is used for conducting full wave lightning impulse voltage tests on various power equipment to verify the insulation performance of the equipment. Output waveform 1.2 ± 30%/50 ± 20% μ s standard lightning impulse voltage full wave, efficiency greater than 90%, overshoot less than 5%; The measurement module integrates waveform evaluation algorithms that comply with IEC standards and can automatically calculate and display waveform parameters.
The KDYD-2845kV Intelligent Turn-to-Turn Withstand Voltage Tester is a digital device designed to test turn-to-turn insulation in motor and transformer windings. It applies high-voltage pulses and utilizes an integrated industrial computer and software to analyze waveforms, intelligently detecting defects such as inter-turn short circuits. Featuring high safety (multiple protections), high precision, and high energy output, this tester is suitable for production and quality control of electrical equipment rated at 15,000V and below, serving as an advanced instrument for intelligent and efficient withstand voltage testing.
Detect and suppress partial discharge (PD) phenomena in high-voltage electrical equipment during factory testing or preventive maintenance, ensuring the insulation performance meets safety and quality standards under high-voltage conditions.
The KDZD3088 Ultrasonic Partial Discharge Online Diagnostic Instrument is an advanced, portable solution for live-line inspection of power systems up to 110 kV. Leveraging high-sensitivity ultrasonic sensors and intelligent signal processing, it detects and analyzes characteristic acoustic emissions from partial discharges caused by insulation defects, contamination, or mechanical issues. Designed for field use—with real-time cloud sync, GPS tagging, and mobile integration—it enables fast, accurate, and non-intrusive PD diagnostics on overhead lines, substations, and rail electrification systems.
Product Overview KDSL-S500A Three-phase Large Current Generator (hereinafter referred to as Three-phase Current Rise) is the test equipment developed by our company. It combines the advantages of similar products at home and abroad. It adopts numerical control technology and has strong anti-jamming capability. Compared with the previous generation of current rise, the converter made of low power consumption and large capacity self-coupling voltage regulator and high permeability iron core has the advantages of large output power, small size and light weight. It is mainly used for calibration of thermal relay, motor protector, contactor, breaker, air switch, switch cabinet, breaker and protection panel.
